To find the surface area of a cylinder, we can use the formula:

\[ \text{Surface Area} = 2\pi r(h + r) \]

where:

  • \( r \) is the radius,
  • \( h \) is the height,
  • \( \pi \) is approximately 3.14.

Given:

  • Height \( h = 8 \) yards,
  • Radius \( r = 7 \) yards.

Now, substituting the values into the formula:

\[ \text{Surface Area} = 2 \times 3.14 \times 7 \times (8 + 7) \]

First, calculate \( (8 + 7) \):

\[ 8 + 7 = 15 \]

Now substitute that back into the formula:

\[ \text{Surface Area} = 2 \times 3.14 \times 7 \times 15 \]

Calculate \( 2 \times 3.14 = 6.28 \):

\[ \text{Surface Area} = 6.28 \times 7 \times 15 \]

Calculate \( 6.28 \times 7 = 43.96 \):

\[ \text{Surface Area} = 43.96 \times 15 \]

Now calculate \( 43.96 \times 15 \):

\[ 43.96 \times 15 = 659.4 \]

Hence, the surface area of the cylinder is approximately \( 659.4 \) square yards.

However, re-checking the options provided:

  1. 252.77 square yards
  2. 329.7 square yards
  3. 577.76 square yards
  4. 252.77 square yards

None of them match the calculated surface area.
